The new TP-6.5 Signature Phono Stage is designed to complement and match the TL-6.5 and TL7.5 Linestage Preamplifiers in sonic performance, user interface and cosmetics. This all-new product was designed from the ground up to redefine the current state of the art in standalone MC step ups and to stand as a reference phono stage worthy of the top VTL linestage preamplifiers, the TL7.5 Series II and TL-6.5.

TP-6.5

The TP-6.5 Series II Signature Phono Preamplifier is a major update and improvement to the TP-6.5 Signature Phono stage. Its upgrades include circuit enhancements originally developed for the acclaimed TL-7.5 Series III Reference Preamplifier, as well as newly designed, more robust power storage for the active MC stage.

The original TP-6.5 Phono preamplifier complemented the top of the line VTL TL-6.5 and TL7.5 Linestage Preamplifiers, matching them in sonic performance, user interface and cosmetics. The new TP-6.5II pushes the analog envelope even further, utilizing the latest innovations from VTL. The result is a phono stage that substantially improves upon the performance of its predecessor.

The phono stage employs hybrid JFET/tube circuitry for quiet operation, multiple low-noise cascaded regulators and shielded power supplies for increased dynamics, accurate 4-corner passive RIAA equalization and 68dB of gain from the balanced outputs, all in a single chassis unit. A wide selection of load and gain settings as well as other input functions are easily accessible via both front panel and remote control.

One of the design breakthroughs in the TP-6.5 II is the use of the shunt regulator in the power supply, which offers superior regulation and ripple rejection and minimizes the sonic impact on the audio signal due to lowered amplification in the regulator. The result is a noticeable lowering of background noise contributing to stability and better delineation of midrange and midbass. There is more air around the voices, more finesse, extension, and nuances – giving an overall more lifelike impression. Especially noticeable improvement in the active MC Stage is its speed and dynamics.

Further improvement in the TP-6.5 Series II comes from the implementation of massive low impedance power supply storage in the active MC stage, fed by multiple cascaded regulators and capacitance multiplier circuits. The resulting rigid, low impedance power supplies prevent power supply ripple and other noise from affecting the sensitive MC signal. The new gel capacitor technology, which offers dramatically higher capacitance in much smaller packages, is key to the breakthrough in the TP6.5 II’s active MC stage directly contributing to its remarkable lower noise level and ability to handle very low output cartridges.

The TP-6.5II also offers a high quality transformer Moving Coil step up option, both to offer a low-noise MC step up, and a second MC stage. This second MC input replaces the original MM input that is normally standard in the TP6.5 Phono Stage, and uses the existing MM input to provide access to the transformer MC step up.

The addition of the step up transformer allows both for appropriate loading for very low-output cartridges, and the flexibility of handling different cartridges with different step up methods, as in some cases certain cartridges can sound substantially better with transformers than they do with active gain stages. The transformer also allows the cartridge to be loaded via the transformer, instead of via the loading resistor, retaining as much of the signal available from these cartridges as possible.

Switching between the inputs is done only after the signal has been amplified, avoiding signal losses inherent in switching the fragile MC signal straight from the cartridge.

This option offers the maximum MC cartridge handling flexibility, and also accommodates multiple arms and multiple MC cartridges, as both inputs can be connected simultaneously.
